Structural Model Of The Technological Process Of Storage And Processing Of Oil Raw Materials, N.A Kabulov

Chemical Technology, Control and Management

The technological method of storing and processing oilseed raw materials is structurally modelled in the article. Additionally, it is suggested that the generalized structure be presented as a three-part scheme, consisting of a raw material department, a processing shop, and transportation networks. On the basis of a thorough examination of the characteristics of the constituent parts of the technological complex, a practical model for the problem of the general characteristics of the technological complex is proposed.

Advances And Challenges On Cathode Catalysts For Lithium-Oxygen Batteries, Bo Wen, Zhuo Zhu, Fu-Jun Li

Journal of Electrochemistry

Aprotic lithium-oxygen batteries (LOBs) with high theoretical energy density have received considerable attention over the past years. However, the oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) at cathodes suffer from slow kinetics for large overvoltages in LOBs. Significant advances on catalysts have been achieved to accelerate cathode kinetics, but understanding on the formation/decomposition processes of Li₂O₂ is limited. Herein, this review highlights the fundamental understanding of the correlation between catalysts and formation/decomposition of Li₂O₂. Various types of cathode catalysts are discussed to reveal the mechanism of formation/decomposition of Li₂O₂, …

Large-Scale Identification And Analysis Of Factors Impacting Simple Bug Resolution Times In Open Source Software Repositories, Elia Eiroa-Lledo, Rao Hamza Ali, Gabriela Pinto, Jillian Anderson, Erik Linstead

Engineering Faculty Articles and Research

One of the most prominent issues the ever-growing open-source software community faces is the abundance of buggy code. Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid …

Understanding The Roles Of Images And Intermodal Relationships For Optimized Use Of Visual And Verbal Resources In Vietnam’S Textbooks For Lower Secondary Levels, Yusnita Febrianti, Thao Vu

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

The study investigates the roles of images and intermodal relationships of both language and images in two English textbooks used in Vietnamese lower secondary schools, namely Tieng Anh and Solutions textbooks to gain insights on the ways to optimise the use of both language and images as resources in teaching and learning activities. Kress and Van Leeuwen’s (1996, 2006) framework on the grammar of visual design is used to analyse the images, looking at the types of image representations and the compositional meanings. The language-image relationships in the books, on the other hand, are analysed using the framework of Intermodal …

Recent Advances In Anode Materials Of Solid Oxide Electrolysis Cells, Geng Zou, Wei-Cheng Feng, Yue-Feng Song, Guo-Xiong Wang

Journal of Electrochemistry

Solid oxide electrolysis cell (SOEC) as an electrochemical energy conversion device has attracted increasing attention due to its large current density, high Faradaic efficiency and energy efficiency. Oxygen evolution reaction at the anode, a four-electron transfer process, is an important half-reaction for SOEC, which contributes to the main polarization resistance and consumes most electric energy during the electrolysis process. Hence, designing anode materials with high activity and stability is crucial for the performance improvement and practical application of SOEC. Recently, some advances have been made in the development of high-performance anode. In the current review, the mechanisms for CO_{2 …}

Anodic Electrocatalysis Of Glycerol Oxidation For Hybrid Alkali/Acid Electrolytic Hydrogen Generation, Xin Feng, Bo-Wen Liu, Ke-Xin Guo, Lin-Feng Fan, Gen-Xiang Wang, Su-Qin Ci, Zhen-Hai Wen

Journal of Electrochemistry

Electrolytic hydrogen production is heavily restricted by high-energy consumption majorly due to the relatively high potential of anodic oxygen evolution reaction (OER). Development of OER-alternative reaction at the anode has been recently proposed as a promising pathway to address the associated issues. In this work, we report a hybrid acid/alkali dual-electrolyte electrolyzer by coupling acidic hydrogen evolution reaction (HER) using commercial Pt/C cathode with alkaline Electrocatalytic glycerol oxidation (GOR) which is implemented by developing a nickel foam (NF) supporting Co₃O₄ nanosheets anode that shows low overpotential and high selectivity toward GOR for formate production. The hybrid acid/alkali …

Highly Dispersed Pt Nanoparticles Root In Single-Atom Fe Sites In Ldhs Toward Efficient Methanol Oxidation, Qing-Cheng Meng, Lin-Bo Jin, Meng-Ze Ma, Xue-Qing Gao, Ai-Bing Chen, Dao-Jin Zhou, Xiao-Ming Sun

Journal of Electrochemistry

Active and durable electrocatalysts for methanol oxidation reaction are of critical importance to the commercial viability of direct methanol fuel cell, which has already attracted growing popularities. However, current methanol oxidation electrocatalysts fall far short of expectations and suffer from excessive use of noble metal, mediocre activity, and rapid decay. Here we report the Pt anchored on NiFe-LDHs surface hybrid for stable methanol oxidation in alkaline media. Based on the high intrinsic methanol oxidation activity of Pt nanoparticles, the substrates NiFe-LDHs further enhanced anti-poisoning ability and maintained unaffected stability after 200,000 s cycle test compared to commercial Pt/C catalyst. The …

Satellite Ligand Effects On Magnetic Exchange In Dimers. A Structural, Magnetic And Theoretical Investigation Of Cu2l2x4 (L = Methylisothiazolinone And X = Cl−, Br−), Stefan Coetzee, Mark M. Turnbull, Christopher Landee, Jeffrey C. Monroe, Mercè Deumal, Juan J. Novoa, Melanie Rademeyer

Chemistry

Halide-bridged polymers have gained significant interest due to their diverse properties and potential applications. Stacked Cu₂L₂X₄ dimers, where L is an organic ligand and X can be Cl⁻ or Br⁻, are of interest because a chloride analogue where L = 2-pyridone, had previously been reported to exhibit bulk ferromagnetism, which augured great potentiality for this class of compounds. The synthesis, structural characterization, magnetic susceptibility measurements, and computational studies of two isostructural CuClMI (MI = methylisothiazolinone) and CuBrMI polymers of Cu(ii), along with a related CuClPYR (PYR = 2-pyridone) is reported. CuClMI and …

Spectral Sensitivity Near Exceptional Points As A Resource For Hardware Encryption, Minye Yang, Liang Zhu, Qi Zhong, Ramy El-Ganainy, Pai Yen Chen

Michigan Tech Publications, Part 1

The spectral sensitivity near exceptional points (EPs) has been recently explored as an avenue for building sensors with enhanced sensitivity. However, to date, it is not clear whether this class of sensors does indeed outperform traditional sensors in terms of signal-to-noise ratio. In this work, we investigate the spectral sensitivity associated with EPs under a different lens and propose to utilize it as a resource for hardware security. In particular, we introduce a physically unclonable function (PUF) based on analogue electronic circuits that benefit from the drastic eigenvalues bifurcation near a divergent exceptional point to enhance the stochastic entropy caused …

Electronic Structure Calculations Of Static Hyper(Polarizabilities) Of Substrate-Supported Group-Iv And -V Elemental Monolayers, Sumandeep Kaur, Ravindra Pandey, Shashi P. Karna

Michigan Tech Publications, Part 1

The substrate-induced effects on the polarizability (α) and first dipole hyperpolarizability (β) of group-IV (i.e., graphene, silicene, germanene, stanene) and group-V (i.e., phosphorene, arsenene, antimonene, and bismuthene) elemental monolayer nanoflakes are investigated. Density functional theory calculations show that these monolayers are bound with varying degrees of interaction strength with the Ag(111) substrate surface. Calculated dipole moment and β values are zero for the centrosymmetric configurations of the pristine elemental monolayers. On the other hand, substrate-induced changes in the electronic densities at the interface lead to substantially enhanced values of β, making these materials attractive for applications in the next-generation photonic …

Choosing Future – Climate Adaptation Justice & Transformation, A.R. Siders

Sustainability Seminar Series

Adaptation to climate change has, to date, generally sought to maintain the status quo. Future adaptation could involve radical shifts in society and socio-ecological systems, but what are the pros and cons of such transformations? What does fair, equitable, or just adaptation involve and is it possible? Dr. Siders will describe emerging dilemmas in the debate about adaptation justice and suggest pathways to envision a broader range of futures we can choose.

Facilitating Tilting As A Faculty Community, Debra Palmer, Carrie Bachhofer, Allen Brown, Alaina Kaus, Michele Mckie, Thelma Sexton

Perspectives In Learning

In this paper, we describe our perspectives and experiences working as one of several small groups within a campus-wide program at our university to help implement transparency in learning and teaching (TILT) principles. Faculty were asked to implement TILT into lower-and upper-level courses, as well as co-curricular activities, by transforming some aspect of their course or activities to be more "transparent," meaning students would be able to better understand its purpose and value and how it relates to their major, future career, and personal lives. The program followed a faculty learning community (FLC) model, where members supported one another through …

Can Tilt Be Used To Teach Study Tactics? A Case Study In A Biology Classroom, Anne Jacobs

Perspectives In Learning

Recently, there has been a movement encouraging instructors in higher education to use the Transparency in Teaching and Learning (TILT) framework when designing assignments. This framework helps instructors clarify their expectations and evaluation criteria. Making assignments more transparent may result in greater student success. However, it is less clear how this framework can be applied to classes that use exams as a main method of assessing student learning. One option might be to use a TILTed assignment to introduce students to learning tools to improve their studying. I did this by giving students in an introductory biology class an assignment …

Design And Performance Analysis Of Dry Gas Fishbone Wells For Lower Carbon Footprint, Habib Ouadi, Aimen Laalam, Amjed Hassan, Abderraouf Chemmakh, Vamegh Rasouli, Mohamed Mahmoud

Petroleum Engineering Student Publications

Multilateral well drilling technology has recently assisted the drilling industry in improving borehole contact area and reducing operation time, while maintaining a competitive cost. The most advanced multilateral well drilling method is Fishbone drilling (FbD). This method has been utilized in several hydrocarbon fields worldwide, resulting in high recovery enhancement and reduced carbon emissions from drilling. FbD involves drilling several branches from laterals and can be considered as an alternative method to hydraulic fracturing to increase the stimulated reservoir volume. However, the expected productivity of applying a Fishbone well from one field to another can vary due to various challenges …

Electrical and Computer Engineering Faculty Research & Creative Works

Detection of Volatile Organic Compounds (VOCs) is One of the Most Challenging Tasks in Modelling Breath Analyzers Because of their Low Concentrations (Parts-Per-Billion (Ppb) to Parts-Per-Million (Ppm)) in Breath and the High Humidity Levels in Exhaled Breaths. the Refractive Index is One of the Crucial Optical Properties of Metal-Organic Frameworks (MOFs), Which is Changeable Via the Variation of Gas Species and Concentrations that Can Be Utilized as Gas Detectors. Herein, for the First Time, We Used Lorentz–Lorentz, Maxwell–Ga, and Bruggeman Effective Medium Approximation (EMA) Equations to Compute the Percentage Change in the Index of Refraction (∆n%) of ZIF-7, ZIF-8, ZIF-90, …

Comparing The Efficacy Of Two Inclusivity Interventions On Willingness To Invest In Female- Versus Male-Led Stem And Non-Stem Companies, Alicia Macchione

Dissertations

A notable gender asymmetry has been historically prevalent in science, technology, engineering, and mathematics (STEM) fields. Recent work has shown how gender-inclusive advertisements can increase women’s interest in pursuing these fields as indexed by college course enrollment, which could occur through reminders of moral and pragmatic utilities of gender inclusivity. This dissertation extended prior work by determining if inclusivity priming can be leveraged to facilitate financial investment in hypothetical STEM and non-STEM companies led by either a male or female CEO. Participants were first primed with a statement describing the pragmatic utility of gender inclusivity in STEM, a moral statement …

Molecular Research In Pancreatic Cancer: Small Molecule Inhibitors, Their Mechanistic Pathways And Beyond, Shaila A. Shetu, Nneoma James, Gildardo Rivera-Sanchez, Debasish Bandyopadhyay

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

Pancreatic enzymes assist metabolic digestion, and hormones like insulin and glucagon play a critical role in maintaining our blood sugar levels. A malignant pancreas is incapable of doing its regular functions, which results in a health catastrophe. To date, there is no effective biomarker to detect early-stage pancreatic cancer, which makes pancreatic cancer the cancer with the highest mortality rate of all cancer types. Primarily, mutations of the KRAS, CDKN2A, TP53, and SMAD4 genes are responsible for pancreatic cancer, of which mutations of the KRAS gene are present in more than 80% of pancreatic cancer cases. Accordingly, there is a …

On Refinements To Qmfd Based Chirp Parameter Estimation, Balu Santhanam, Thalanayar Santhanam

Electrical & Computer Engineering Technical Reports

Commuting matrix methods furnish a full basis of orthog- onal eigenvectors for the discrete Fourier transform or its centered version needed for computing the discrete fractional Fourier transform and multicomponent chirp signal analysis. However, these approaches suffer from ill-conditioning issues at higher matrix sizes, and require a computationally expensive eigenvalue decomposition.

In this paper, ill-conditioning issues associated with the QMFD approach developed previously by the authors are addressed via diagonal modification. Further symmetries of the eigenvectors are used to reduce the size of the underlying eigenvalue problem. These modifications are then incorporated into the real-arithmetic implementation of the QMFD approach …

Terada Torahiko, A Physicist And A Haikai Poet, Akira Komiya

CLCWeb: Comparative Literature and Culture

Terada Torahiko is known as a scientific essayist in Japan, but hardly anyone knows he was a haikai poet as well as a physicist. According to him, haikai poetry and physics are two different ways of conceiving Nature, both valid and perhaps complementary to each other. Seeing his research in physics looking for regularities in apparently irregular phenomena in everyday life, we may say his haiku haikai spirit is manifest there and that he was pioneering a new science such as the one developed later by Ilya Prigogine. His association of haiku haikai poetry and Freudian interpretations of dreams leads …

Bergson On Poetics: Philosophy, Literature And Science, Michel Dalissier

CLCWeb: Comparative Literature and Culture

In this paper, I analyze Henri Bergson’s insightful and contrasted vision of poetry. First, I show in what sense Bergson sympathizes with the idea that the poet must be credited to surpass the novelist in offering to us an unparalleled emotional apprehension of the world. Second, I nonetheless underline how Bergson grants the product of the poet, i.e., the poem itself, a problematic linguistic status, inasmuch as the focus of his analysis shifts from an intersubjective poetical apprehension of feelings to their individual poetic appreciation, or from the spiritual dimension of poetry to its material dimension. Third, I further suggest …
